I have to stop doing this thing where I start reading an article, and do a breadth-first traversal of all the related articles it links to. I may get a better picture than just reading the single article, but god damnit.

@axiom you would probably be right. The formula (and thus the program) is given by defining a function Fib(n) that returns \((phi^n) - (-phi)^(-n))/sqrt(5)\ where phi = the Golden ratio, and the returned number is the nth Fib number

@axiom the drawback however is that the formula uses the Golden ratio, which is infinitely long, so after some n the program fails in returning the correct nth Fib number due to the computers finite precision
